math-sonify v1.3.0 — 53 Systems, Hyperchaos, New Scales

What's new in v1.3.0

New dynamical systems (7)

• Shimizu-Morioka — two-scroll attractor driven by x²
• Genesio-Tesi — third-order Jerk circuit; one x² term creates chaos

• Sprott K — xy product; one of Sprott's minimal chaotic flows

New musical scales (5)

• Natural Minor (Aeolian)
• Harmonic Minor (raised 7th)

Bifurcation diagram

• Full integration test coverage for all new systems
• All-presets load/validate test

Install

cargo install math-sonify

v1.0.4 — Behavioral Layers, Coherence Budget, Scene Export

What's new in v1.0.4

Behavioral Layer Toggles

9 invisible behavioral modifiers are now toggleable in the Advanced panel (BEHAVIORAL LAYERS section): Time of Day, Seasonal Drift, Volume Creep, Breathing, Circadian Sleep, Dreams, Aging, Typing Resonance, Instance Empathy.

Arrangement Coherence Budget

Generated songs now anchor a root key, scale family, and tempo region across all scenes — songs feel like a coherent journey instead of 6 random patches. Reverb is drawn from a shared budget to prevent mud.

Per-Scene Audio Export

Each active scene in the Arrange tab has an ⬇ Export button — records exactly that scene's morph + hold duration to a timestamped WAV file.

Square & Noise Waveforms

Two new oscillator shapes available via voice_shapes config: square (PolyBLEP band-limited) and noise (white noise).

Stability

• Attractor divergence detector auto-resets and shows a toast notification
• Dream mode validates config bounds before applying
• deny(unsafe_code) at crate level

Tests

• Golden audio regression tests (oscillator determinism + amplitude bounds)
• Config hot-reload test coverage

v1.0.3 — 📼 Snippet Studio

📼 Snippet Studio — FL Studio-style snippet workflow

How it works:

1. Generate sounds you like using any attractor + sonification mode
2. Open the 📼 Studio tab
3. Choose a capture duration (4s / 8s / 16s / 32s)
4. Press ⏺ Capture Snippet — saves the last N seconds of live audio to snippets/ as a WAV
5. Your snippet appears in the Library with a waveform thumbnail and a unique color
6. Click snippets to rename them, or click the ✕ to delete
7. Select a snippet in the library, then click any numbered slot in the Song Grid to place it
8. Fill in the slots to compose your song structure (32 slots, 2 columns)
9. Press ▶ Play Song to sequence through the slots in order
10. Enable ↺ Loop to cycle continuously; adjust Vol for playback level

Technical details

• Snippets are mixed directly into the master audio output by the audio thread
• Song sequencer runs at UI thread rate (~30 Hz), advancing slots when each finishes
• All snippets saved as 32-bit float stereo WAV to the snippets/ folder in the app directory

v1.0.2 — System param UI + EQ wiring

What's new

• Parameter sliders for all 5 new systems: Mackey-Glass DDE (β, γ, τ, n), Nose-Hoover (a), Sprott B (info), Hénon Map (a, b), Lorenz-96 (F forcing) — all accessible in Advanced > Physics Engine > Parameters
• 3-Band EQ now fully connected: Low shelf / Mid peak / High shelf sliders in Advanced > Effects now actually affect the audio output
• All system parameters persist — config structs added so params survive system switches
• Desktop .exe updated

v1.0.1 — Full audit build: 5 new systems + DSP fixes

v1.0.1 — Comprehensive audit build

Includes all changes from the UI overhaul (v1.0.0-ui) plus:

5 New Dynamical Systems

• Mackey-Glass DDE — delay differential equation (ring buffer approximation)
• Nose-Hoover — thermostat attractor
• Sprott B — compact chaotic system
• Henon Map — 2D discrete chaotic map
• Lorenz-96 — N-dimensional atmospheric model

DSP Fixes

• Bitcrusher — triangular dither for smoother quantization, integer counter for even timing
• Portamento — proper RC-filter exponential smoothing (was incorrect linear interpolation)
• VU meter — proper 300ms ballistic peak decay
• Stereo width — energy-preserving normalisation at wide settings
• Grain spawn rate — smoothed low-pass update, prevents clicks on fast changes
• 3-band EQ added to master effects chain

Analysis Tools

• Lyapunov spectrum — live computation every 5s, displayed in Math View
• Poincaré section utility function
• Period detection utility function
• 2D bifurcation mode (sweep two parameters simultaneously)

Fix: deadlock + NaN guard on portrait trail

• Fixed potential deadlock in instance-empathy nudge code (two separate shared.lock() calls in one statement)
• Added NaN/inf guard to portrait trail push so diverging attractors don't corrupt the visualization
• Both fixes improve crash resilience when using Evolve mode
